long, and at once recognized by its stout fore legs, which 

 are admirably adapted for digging. It burrows in the 

 moist ground, raising ridges in its search for insects, on 

 which it preys. 



The Genus Gryllns contains the Field Crickets, which 

 are dark colored or black ; and CEcanthus, the Climbing 

 Crickets, as in Fig 343, which are light colored. 



LOCUSTARI^E, Latr., OR LOCUST FAMILY. --This Fam- 

 ily embraces grasshopper-like orthoptera which have very 

 long, slender antennae, four-jointed tarsi, and the females 

 have a long ovipositor. Many of them produce a stridu-

The Genus Ceutkophilus contains those which are wing-' 

 less, and live in concealment under stones, a dozen species 

 of which are enumerated by Scudder. 



The Genus Cyrtophyllus has the wing-covers much wi- 

 dened in the middle, and concave. 



The Katydid, C. concavus, Scudd., is one inch and a
